V 1.2 VDC/ max. 100 mA, V
ON
Outputs connectable to total and/or partial meters.
Pulse duration: 220 ms (ON),
DIN43864.

output and measuring inputs, 4000 V
and power supply input.
Notes: the outputs can be open collector type or relay type
(for the relay output refer to the characteristics described in
